T Coronae Borealis (T CrB), informally nicknamed the Blaze Star,[3] is a recurring nova in the constellationCorona Borealis. It normally has a magnitude of about 10, which is near the limit of typical binoculars. It has been seen to outburst twice, reaching magnitude 2.0 on May 12, 1866 and magnitude 3.0 on February 9, 1946.[4] Though a more recent paper shows the 1866 outburst with a possible peak range of magnitude 2.5 ± 0.5.[5] Even when at peak magnitude of 2.5, this recurrent nova is dimmer than about 120 stars in the night sky.[6]
